Background: In the 2020 GLOBOCAN report, breast cancer is the 3rd most common cause of cancer-related mortality in the Philippines. The incidence of breast cancer in the young (≤40 years) was reported to be higher in the Philippines compared to other Asian countries. Several studies have consistently demonstrated poor survival outcomes in this age group due to its aggressiveness and unique tumour biology.

Introduction: Newer extraperitoneal techniques of laparoscopic ventral/incisional hernia repair (LVIHR) have been continually introduced since the popularity of the laparoscopic intraperitoneal onlay mesh technique began in 1993. One of which is the extended totally extraperitoneal (eTEP) approach allowing wide mesh augmentation, concurrent repair of diastasis recti, and performance of transversus abdominis release (TAR) for large/complex hernias. However, minimally invasive/laparoendoscopic ventral hernia repair is not yet widely adopted in the Philippines.

The creation of the surgical space in transoral endoscopic thyroid surgery may put the anterior jugular vein at risk for injury and possibly lead to carbon dioxide (CO ) embolism. Although rare, CO embolism is potentially fatal. We report a case of a 67-year-old female who underwent transoral endoscopic thyroidectomy vestibular approach (TOETVA) for a benign thyroid disease.

Since 2016, the transoral endoscopic thyroidectomy via vestibular approach (TOETVA) has gained popularity due to being a true 'scarless' procedure. However, minimally invasive thyroidectomy has not been widely adopted in the Philippines yet.

Local data mainly on laparoscopic adjustable gastric banding (LAGB) and Roux-en-Y gastric bypass (RYGB) are limited as well.

Purpose: This study aimed to share our experience with SLNB in the Filipino population with early breast cancer.

Patients And Methods: A retrospective review was done on all patients with confirmed invasive breast carcinoma, tumor size of 5 cm or less (T1/T2), who preoperatively had no clinical signs of axillary metastasis and subsequently underwent SLNB with blue dye method from January 01, 2008 to December 31, 2017. Clinicopathologic profiles were recorded.
